摘要： This invention is to plasma arc weld using a keyhole mode to build a partially-penetrated keyhole and then a melt-in mode to finally reach the full penetration before switching to the base period. The full penetration is thus established during the peak period in two stages: keyhole stage and then melt-in stage. While the keyhole stage helps reduce the heat inputs and weld puddles, the melt-in stage finishes the full penetration at reduced impacts from the plasma jets producing the desired weld bead geometry and regularity. The duration of the melt-in stage is automatically determined using arc signals to assure the full penetration. In comparison with keyhole PAW, bead geometry and regularity are significantly improved with slightly increased net heat inputs. In comparison with melt-in PAW and GTAW, the net heat input is reduced approximately forty percent.

摘要翻译： 本发明是使用键孔模式来等离子体电弧焊，以构建部分穿透的钥匙孔，然后是熔化模式，以在切换到基准周期之前最终达到完全穿透。 因此，高峰期的完全渗透分为两个阶段：锁眼阶段，然后融入阶段。 虽然钥匙孔阶段有助于减少热量输入和焊接水泥浆，但是熔化阶段在等离子体射流产生所需焊缝几何形状和规则性的冲击下完成了完全穿透。 使用电弧信号自动确定熔入阶段的持续时间，以确保完全穿透。 与钥匙孔PAW相比，珠粒几何形状和规则性明显改善，净热输入略有增加。 与熔融PAW和GTAW相比，净热输入减少了约40％。

摘要： In gas tungsten arc welding (GTAW), the achievable deposition rate of the filler wire is coupled with the arc energy and the mass of the molten metal in the weld pool. In this invention, a side arc is added into the GTA (gas tungsten arc) between the wire and the same tungsten that establishes the GTA with the work-piece. While its anode provides a GMAW (gas metal arc welding) melting mechanism to completely melt the wire at high speeds, the undesirable dependence of deposition rate on the weld pool mass is also eliminated. As a result, the deposition rate is increased and the ability to provide desirable deposition rate and base metal melting/penetration freely without coupling is established for the GTAW.

摘要： The invention discloses a method to determine the weld joint penetration from arc voltage measurements in gas tungsten arc welding (GTAW). It is based on an observation on the dynamic weld pool surface in GTAW—the surface tends to first expand toward the electrode and then be pushed away from the electrode after full penetration is established. For the pool surface in GTAW, localized partial keyholes around the arc axis as in plasma arc welding are not significant. The pool surface is relatively smooth. The arc voltage that reflects changes in the arc length thus first tends to reduce and then increases after full penetration is established. This invention thus tracks the arc voltage until the decrease slope becomes insignificant. Once full penetration is established, the current is reduced to decrease the weld penetration or first decrease the penetration growth for a certain period and then decrease the weld penetration.

摘要： For fillet welding, sufficient amounts of metal must be deposited in order to make welds with sufficient sizes. In conventional submerged arc welding (SAW), the heat input is proportional to the amount of metal melted and is thus determined by the required weld size. In order to reduce the needed heat input, Double-Electrode SAW (DE-SAW) method is used for fillet joints. To minimize the heat input required to produce the welds with required geometry and sizes, a gap is introduced between the panel and the tee forming a modified fillet joint design. The use of the gap improves the ability of DE-SAW to produce the required weld beads at reduced heat input and penetration capability. Major parameters including the gap, travel speed and heat input level have been selected/optimized/minimized to produce required fillet weld beads with a minimized heat input based on qualitative and quantitative analyses.

摘要： A control system for a welding process controls the current applied to the welding torch in either a manual or automatic welding system. The arc voltage is monitored to determine when full penetration of the weld pool has occurred so that the current to the welding torch can be stopped. The arc voltage or the slope of the increase of the arc voltage can be used to operate the control algorithm. Additional variables such as torch speed, torch angle, and weld position can be used to influence the control algorithm. The contemplated systems include both GTAW and PAW welding process as well as others.

摘要： A solid object is rotated in the central pool of molten metal that is formed by using an arc to melt a continuously fed metal wire and depositing the melted wire between the facing edges of two base metals to be joined. The stirring generated by the rotation in the pool moves hotter metal in the central region to its boundary adjacent to the facing edges. This stirring generated movement of molten metal is expected to better heat the facing edges so that the molten metal can better fuse with the facing edges. The stirring generated fluid flow within the molten pool also changes the solidification of the molten metal and the formation of the resultant grains.

摘要翻译： 本发明公开了一种用于确定气体钨弧焊（GTAW）中的电弧电压测量的焊接接头穿透的方法。 它是基于在GTAW中的动态熔池表面的观察 - 表面倾向于首先向电极膨胀，然后在完全穿透之后被推离电极。 对于GTAW中的池表面，等离子体中弧线轴周围的局部部分键槽不是很重要的。 游泳池表面相对光滑。 因此，首先反映电弧长度变化的电弧电压趋于减小，然后在完全穿透之后增加。 因此，本发明跟踪电弧电压，直到减小斜率变得不显着。 一旦完全穿透，电流就会降低，以减少焊接穿透，或者首先降低穿透速度一段时间，然后降低焊缝穿透度。 3
